基本例句
荧光屏
For instance, the phosphor on a CRT screen needs to be constantly reactivated by an electron beam in order to remain illuminated.例如，阴极射线管荧光屏上的磷光体为了保持它激发光状态，需要用电子束不断地再激励。
As a photon collides with a detector plate, the metal ejects several electrons that are then amplified into a cascade of electrons that light up a phosphor screen.当光子与探测器板材碰撞，释出数个电子，而后这些电子被放大成电子流形成一个荧光屏。 |
